The Liaoshang gold deposit, located in Yantai, eastern Shandong Province, is of medium size. Its ore bodies occur in the contact zone between the Neoproterozoic Linglong super-unit granite and the Paleoproterozoic Jingshan Group, where skarn-type minerals were formed and ore bodies were controlled by structure of the contact zone. The exposed quartz monzonitic diorite is the only Mesozoic intrusive rock. In this paper, the authors studied the characters of each ore body on a macro scale. The result shows that the gold ore body is associated with the quartz monzonitic diorite and not directly related with Neoproterozoic Linglong super-unit granite. By studies of the ore’s micro-characteristics, the authors find that gold primarily precipitated in the quartz-carbonate-sulfide stage and the main types of ore include quartz-calcite-pyrite vein type and pyritized fragmented monzonitic granite type. The quartz-calcite-pyrite vein type is a rich ore.
